Conversion formula

The conversion factor from decimeters to kilometers is 0.0001, which means that 1 decimeter is equal to 0.0001 kilometers:

1 dm = 0.0001 km

To convert 3221 decimeters into kilometers we have to multiply 3221 by the conversion factor in order to get the length amount from decimeters to kilometers. We can also form a simple proportion to calculate the result:

1 dm → 0.0001 km

3221 dm → L_(km)

Solve the above proportion to obtain the length L in kilometers:

L_(km) = 3221 dm × 0.0001 km

L_(km) = 0.3221 km

The final result is:

3221 dm → 0.3221 km

We conclude that 3221 decimeters is equivalent to 0.3221 kilometers:

3221 decimeters = 0.3221 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 3.1046258925799 × 3221 decimeters.

Another way is saying that 3221 decimeters is equal to 1 ÷ 3.1046258925799 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that three thousand two hundred twenty-one decimeters is approximately zero point three two two kilometers:

3221 dm ≅ 0.322 km

An alternative is also that one kilometer is approximately three point one zero five times three thousand two hundred twenty-one decimeters.
